Be it known that l, EARL H. .tlJtMES. e,

oitizen of the United btates, residing at mittetl at the front of onautomobile entl til tlmwn oli' thi rmgh the medium of o rooted about theeylinlere of the engine, the

op imretiie being oonstmiotetl to supply air about the respectivecylinders intle; tlei'itl v of each other onrl the mllnitti'atl en."

construction of which is novel in form sotlmt it can he epplietl to oninternal oomlms-- tion ei'mine employed in. automobiles witl'nnitneoeeeitating; any material chamjg'es or eltei'm tions in theconstruction of the engine and when. so applied will client thecirculation of air about the cylinders thereof in it unique manner sothat all danger of freezing in cold Wtiillllllll? is eliminated, the useof the usual water jackets about the cylinders of the en gineei'eentirely dispensed with.

A further object of the im ention is the provision of an apparatus ofthis character the e] :3 inlet zvhieh is "teir. ontieente indepenilentlyof each other into the housing or t g hoot the 4:;yli1'nie13 oi? aminternal (.UllllllilSlh. i. engine so that intlii'iolnn-l oui'rente ofit'll will circulate about the .iyeepective UYliTiClfilS and thereafterbe drawn oil' to avoid the heating oi? the min, thus maintaining tl' eengine cool at all times, the air being mlniitteil oonetentlv about theengine while in o fiei'ntioh.

A still further objeot of the invention ie' the provision of anapparatus of this char acter which is comparatively simple incometrnetioio, thoroughly reliable and, ellieient in Specification, ofLetters Potent.

Arranged in the interior of the cinduit are vertical and transverse dividing walls or partitions l3 and14 respectively, which terminate as shown by dotted lines in Figs. 1 and2 of the drawing,

thereby dividing the conduit into plural passages, according to thenumber of cylinders of the engine, and leading from these passages arethe connecting tubes 15 which are tapped or otherwise engaged in the topof the housing or jacket 6 for directing independent air currentsflowing through the respective passages and connecting tubes 15 to theother cylinders of the engine so that these cylinders will receiveseparate air currents independently of each other, the air beingadmitted through the intake mouth 5 of the conduit 8 as will beapparent.

Arranged at one side of the housing or jacket 6 is a hot air manifold 16having the terminal branches 17 tapped or otherwise engaged with thejacket (3 for the communication of said hot air manifold '16 with theair spaces formed by the housing or jacket 6 about the respectivecylinders of the on glue, the manifold 16 being held secure by brackets18 and connected immediately with this manifold is an outlet pipe 19suitably secured in place by the cleats 20 carried by the-housing orjacket 6, the pipes 19 being directed forwardly and connected at itsfree end with the hollow hub 21 of a suction tan 22 journa'led insupports 23 and 24 respectively, thefan 22 being formed with dual seriesof blades 25 and 26 respectively, one of the blades 26 being shown indetail in Fig. ,4; of the drawing and these blades 25 and 26 areradially arranged in the fan whcel 22 for the drawing of the hot airfrom the manifold 16, through pipe 19 and exhausting it atthe peripheryof the tan wheel, the hot air being drawn in the fans centrally of thesame. Motion is imparted to the fan 22 through the medium of a sprocketchain 27 WlliCh is driven from a countershal't 28, geared at 29 to thepower shaft 30 of the engine, it being understood of course that it, ispreferable to inclosc the gearing 2.) and other driven parts between theengine and the fan and to lubricate the same automatically in anysuitable manner.

In the operation of the apparatus atmos pheric air is admitted throughthe mouth 5 of the conduit 8, thence conveyed through the neck 12 andtubes 15 into the jacket or housing 6 for circulation in the air spaces7 about the cylinders A of the engine, the

hot air being drawn oil through the manifold 16, pipe 19 and suction fan"22, thereby maintaining the engine cool at all times and eliminatingall danger of l'rcczcing in cold weather as the usual water coolingsystem is entirely dispensed with. .lly reason of the construction andthe employment ol the air cooling apparatus a considerable saving in theconsumption of gas for the working of the engine is bad and thej'icrlcct working thereof is assured.

From the foregoing it is thought that the construction and manner ofopcration oi the apparatus will be clearly understood and a moreextended explanation has been omitted.

What is claimed is:

1. The combination with an internal combustion engine having multiplecylinders and a hood of an auton'iobilc open at its trout, of an aircooling apparatus comprising a jacket covering the cylinders of theengine and divided into separate chambers for the respective cylindersand forming air circulating spaces about said cylinders, alongitudinally, rcarwardly tapered air con duit superposed relative tothe jacket and having independent air passages communicating with therespective chambers oi the jacket at the location of the respectivecylinders, a reticulated flared intake mouth on the conduit and arrangedin. the open end of the hood, and suction means for drawing oft hot airfrom tho jacrct and operated by the engine.

2. The combination with an internal combustion engine having multiplecyliudcri-e and a hood of an automobile open at its front, of an aircooling apparatus comprising a jacket divided into chambers covering therespective cylinders oi the engine and. forming air cic ating spacesabout said cylinders, a longitudinal, tupcrcd air conduit superposedrelative to the jacket and having imlcpclnlcnt air passagescommunicating with the respective chambers of the jacket at the locationof the rcspm'tivc cylinders. a. reticulated flared intake mouth on theconduit and arranged in the open end of the hood, :1 hot air manifoldhaving branches connected with the respective chambers of the jacket forcommunication therewith at the top of the respective cylinders of thecupine, an outlet pipe leading from the manifold, and a suction tanhaving a hollow hub connected with the outlet pipe for exhausting airtherefrom by the fan when active.
